  // .NAME vtkTIFFWriter - write out image data as a TIFF file
  // .SECTION Description
  // vtkTIFFWriter writes image data as a TIFF data file. Data can be written
  // uncompressed or compressed. Several forms of compression are supported
  // including packed bits, JPEG, deflation, and LZW. (Note: LZW compression
  // is currently under patent in the US and is disabled until the patent
  // expires. However, the mechanism for supporting this compression is available
  // for those with a valid license or to whom the patent does not apply.)
